The frog head is important because the nares/nostrils are located at the tip of the head. Without being able to breathe, the frog could not go under water.
It makes it easier for the frog to swallow its prey.
The frog likes to be in water and eyes on the top of the head help to see what is coming. Crocodiles also have them there.
the frog will kill you.
On it's head
A poison arrow (or other frog) does not have ears per sebut has what is called a tympanum on their head behind each eye. It picks up vibrations and transfers them into the inner part of the frog's head where the rest of the organs of hearing are located. Recall that the frog's "ears" have to work under water, and the "ear" of a frog (or toad) is completely covered by the tympanum. The frog's other hearing organs are behind the tympanum in the inner head. Got links if you want 'em.
Because a frog doesn't have a neck as such, it's basically a lump of a body with legs.
It is not necessary, but this can help hold the frog in place more efficiently.
The frog is separated into four parts; head, trunk, forelimb and hind limb. The head only has two muscle sections while the others have between five and seven.
the frog has died or has fliped over
a rabbit, frog, or grasshopper, to name a few.
All frogs have one head.
